Hi Everybody ,

First of all , Merry Christams and I hope  a happy new year for everybody.

May be already answered but I couldn't find it . I tried to read data
from UART0 by initializing exactly based around Insider Guide  book
from Hitex . I could not receive data by Hyperterminal . After
checking all parameters , I used  Oscilloscope and I had serial data
with correct baud rate .  Another software was used but the same
problem exist.

I tried to read data by loop baking UART0 and 1 .  ( only connecting
2< - - > 3) with the same initializing  and I saw  serial data on line.
By overriding putchar ( ) for writing data and getchar ( ) to read
data but it didn't read anything . Any advice is welcomed , it's my code ;

void UART0 (void)	
{
PINSEL0 = 0x05; 		// Select TxD and RxD on pin connect block
U0LCR = 0x80;			//Enable programming of divisor latches

U0DLL = 0xC2;			//Program the divisor latch for 19200 baud
U0DLM = 0x00;

U0LCR = 0x33;			//Program the line control 8\N\1
U0FCR = 0x4F;			//enable the FIFO's

}
void UART1 (void)
{
PINSEL0 |=0x050000;
U1LCR = 0x80;			//Enable programming of divisor latches

U1DLL = 0xC2;			//Program the divisor latch for 19200 baud
U1DLM = 0x00;

U1LCR = 0x33;			//Program the line control 8\N\1
U1FCR = 0x4F;			
} 

int putchar (int ch) 
{                    /* Write character to Serial Port  */
  
  if (ch == '\n')  
  {
    while (!(U0LSR & 0x20));
    U0THR = CR;                          /* output CR */
  }
  while (!(U0LSR & 0x20));

  return (U0THR=ch);
}

int getchar (void)
{
   while(!(U1LSR & 0x01 ));
   return (U1RBR);
}
